This problem has been asked many times here, but none of the solutions work for me, because my XML layout is a bit different.
I have an XML with LinearLayout containing an ImageView and a TextView. The XML is populated using Java code. It is a file picker library from here, it lists the files and folders that exists in the android filesystem.
Here is the XML:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="horizontal" >
<ImageView
android:id="#+id/file_picker_image"
android:layout_width="40dip"
android:layout_height="40dip"
android:layout_marginBottom="5dip"
android:layout_marginLeft="5dip"
android:layout_marginTop="5dip"
android:contentDescription="#string/app_name"
android:scaleType="centerCrop"
android:src="#drawable/file" />
<TextView
android:id="#+id/file_picker_text"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_marginLeft="10dip"
android:singleLine="true"
android:text="#string/file_name"
android:textSize="28sp" />
</LinearLayout>
Now, I want to add a button just below this list. When I try to add the button in the XML, it iterates though each row, and buttons are shown in every row.
When I do it using Java code, neighter the button, nor the textview is displayed, but the image view is displayed.
What I want is similar to the image in this post, but cannot achieve it till now. None of those solutions or any other that I read here works in my case.
I am trying to add the button using this code in the Activity whose source is in the link provided above. I tried to add the following code in FilePickerListAdapter's constructor.
RelativeLayout relLayout = new RelativeLayout(context);
RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT);
params.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM);
Button filterBtn = new Button(context);
filterBtn.setText("Filter");
relLayout.addView(filterBtn, params);
Please guide me what am I doing wrong, and how to make it possible.
Regards.
Mixing the xml way and programmatic way to create views is not a good idea. You might as well create all views in xml first (including your button), only set your button to android:visibility="gone" to hide it. Set it to visible when you want.
This might not be something you asked for, but it's an alternative that you can try it out. I implemented layout_weight into your xml and included the button at the end of the screen. The outcome of this will be something similar with the link in your question.

I've got a need to display and TextView (label), EditText(Input) and TextView(suffix) in a line.
The issue I have is - if the label TextView is too long it The EditText and Suffix TextView and not drawn.
Here's my code.
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_gravity="center_vertical"
android:layout_width="fill_parent"
android:layout_height="wrap_content">
<TextView
android:layout_weight="0"
android:padding="5dp"
android:text="Label"
android:id="#+id/label_text_view"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
<EditText
android:layout_weight="1"
android:id="#+id/input_edit_text"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textColorHint="#color/dark_grey"
android:textColor="#color/black"
android:hint="text.." />
<TextView
android:padding="5dp"
android:layout_weight="0"
android:text="Suffix.."
android:background="#color/lite_grey"
android:id="#+id/suffix_text_view"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
So what I want is - even if the label is over 2-3 lines, for an EditText to appear followed by another TextView.
Any pointers would be appreciated.
Thanks!
Edit:
I've added some 'diagrams' so you can understand what I want to do a bit better.
The label to the EditText can be arbitrary length(2/3 lines), so whenever the label finishes I want an EditText to start (which is followed by another TextView showing a suffix..)
..
![This shows a 2 line label and TextView..]
Edit 2: Thanks for the responses guys!! I think #questioner has really understood what I want to do i.e. I want your 3 views to move to other lines so that they behave like they were one view - and as he has suggested i'll have to find a library for this!
How about this:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_gravity="center_vertical"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<TextView
android:padding="5dp"
android:text="Label"
android:id="#+id/label_text_view"
android:layout_width="100dp"
android:layout_gravity="center_vertical"
android:layout_height="wrap_content"/>
<EditText
android:layout_weight="1"
android:id="#+id/input_edit_text"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical"
android:textColorHint="#color/dark_grey"
android:textColor="#color/black"
android:hint="text.."/>
<TextView
android:padding="5dp"
android:text="Suffix.."
android:layout_gravity="center_vertical"
android:background="#color/lite_grey"
android:id="#+id/suffix_text_view"
android:layout_width="100dp"
android:layout_height="wrap_content"/>
</LinearLayout>
If you want your 3 views to move to other lines so that they behave like they were one view - you should use external library for that.
Why not use a RelativeLayout instead of LinearLayout and then use android:layout_below="#+id/..." or android:layout_above="#+id/..." also android:layout_toRightOf="#+id/..." or android:layout_toLeftOf="#+id/..."
Set
android:layout_weight="1"
for each view so that they all occupy the same amount of horizontal space.
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_gravity="center_vertical"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:weightSum="1">
Try this or please expand a little more.
I'm trying to set my TextView to the left of an ImageButton, but I can't seems to find this option.
I was expecting to use something like android:layout_alignLeft, but this option is missing.
I've tried to google the issue, but couldn't find any relative results.
Without it my TextView overlaps the ImageButton and I want to avoid it.
UPDATE
The full xml code is too complex, but here is the important part of it:
<FrameLayout
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:layout_alignParentLeft="true"
android:background="#color/white"
android:layout_marginLeft="8dp"
android:layout_marginTop="8dp"
android:layout_marginBottom="8dp"
android:layout_toLeftOf="#+id/frameLayoutBalanceClosed">
<ImageButton
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/button_edit_nickname"
android:id="#+id/card_closed_control_editNickname" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/card_closed_description_nickname"
android:layout_margin="8dp" android:layout_gravity="left"/>
</FrameLayout>
I think what you need is a RelativeLayout. You can specify your TextView to the left of your ImageView with it's specifications. Your code would look something like this:
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<TextView
android:id="#+id/text"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_toLeftOf="#+id/imagebutton1" />
<ImageButton
android:id="#+id/imagebutton1"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</RelativeLayout>
The reason FrameLayout isn't working is because it's purpose is to overlay items on top of each other, which wouldn't work at all!
If that isn't what you're looking for, you could also use a TableLayout in which items are arranged in columns.
I would like to align two buttons on the bottom of a relative layout that is wrapped inside of a linear layout.
I am unable to get the view favorites button to be on top of the search button. There is a big space as you can see in this image:
Here is my code:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<TextView
android:text="#string/SearchRestaurantsCity"
android:textAppearance="?android:attr/textAppearanceMedium"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:id="#+id/tvRestaurantSearchCity" />
<EditText
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:id="#+id/etRestaurantSearchCity" />
<TextView
android:text="#string/SearchRestaurantsState"
android:textAppearance="?android:attr/textAppearanceMedium"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:id="#+id/tvRestaurantSearchState" />
<EditText
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:id="#+id/etRestaurantSearchState" />
<TextView
android:text="#string/SearchRestaurantsCategories"
android:textAppearance="?android:attr/textAppearanceMedium"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:id="#+id/tvRestaurantSearchCategories" />
<Spinner
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:id="#+id/spRestaurantSearchCategories" />
<RelativeLayout
android:id="#+id/InnerRelativeLayout"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_alignParentBottom="true">
<Button
android:text="#string/btnViewFavoriteRestaurants"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:id="#+id/btnViewFavoriteRestaurants"
style="#style/ButtonText"
android:padding="5dp"
android:layout_below="btnSearchRestaurants" />
<Button
android:text="#string/btnSearchRestaurants"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:id="#+id/btnSearchRestaurants"
style="#style/ButtonText"
android:layout_alignParentBottom="true"
android:padding="5dp" />
</RelativeLayout>
There are 2 things wrong with the XML.
For starters, you can't refer to the button btnSearchRestaurants before it's defined.
Secondly, you've defined btnSearchRestaurants to align-parent-bottom, and then tried to define that btnViewFavoriteRestaurants would be below that button. It should be above it (as per your description).
If you're trying to put the first button I can see inside RelativeLayout, I'd try to change the following line:
android:layout_below="btnSearchRestaurants" />
for this one:
android:layout_above="#+id/btnSearchRestaurants" />
Part of the space is reserved for all the elements of the layout I can see inside the LinearLayout,and the + is because the button btnSearchRestaurants is below so it is not created yet
I think the problem is at
android:layout_below="btnSearchRestaurants"
It should be
android:layout_below="#id/btnSearchRestaurants"
In your xml code I think you should correct this line
android:layout_below="btnSearchRestaurants"
as you want it to be above the Search Restaurants button it should be
android:layout_above="#id/btnSearchRestaurants"
I changed below to above for obvious reasons (you want it above the other button not below it) and added #id/ because you will be searching for the button id.
I try to put a regular button inside an image in android XML. How can it be done? I tried something like this:
<ImageView .......
<Button .... />
</ImageView>
where the dots represent code. Apparently this is not the way because the platform threw an exception.
Can anyone help?
Use relative layout to insert button on the image.
your image should be given in background tag of RelativeLayout.
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="50dp"
android:background="#drawable/list_nav"
>
<Button
android:layout_width="63dp"
android:layout_height="36dp"
android:id="#+id/mapbutton"
android:layout_marginTop="7dp"
android:layout_marginLeft="4dp"
android:layout_alignParentLeft="true"
/>
this Example adds button on left side of the image since i used layout_alignParentLeft="true"
You can use FrameLayout:
<FrameLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/linearLayout1"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<ImageView android:id="#+id/myImage"
android:layout_height="fill_parent"
android:layout_width="fill_parent"
android:src="#drawable/icon" />
<Button android:id="#+id/myButton"
android:layout_width="150dip"
android:layout_height="150dip"
android:text="My Button"/>
</FrameLayout>
You don't write why you need image and button. Do you know about ImageButton?
#Uriel Frankel you may try creating a custom ImageView either.Here is a post regarding Creating Custom ImageView.
Hope it helps.
I have a header where I have the text: "Huidige Locatie" and beneath that I have an image of a country flag.
I declared the TextView and ImageView in the layout as follows:
<LinearLayout
android:id="#+id/locatiebalk"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:paddingTop="5sp"
android:orientation="horizontal">
<LinearLayout
android:id="#+id/vlaggenlocatie"
android:layout_width="105sp"
android:layout_height="fill_parent"
android:paddingLeft="14sp"
android:orientation="vertical">
<TextView
android:id="#+id/huidiglocatie"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="Huidige locatie"
android:textColor="#000000"
android:textSize="12sp"/>
<ImageView
android:id="#+id/flag"
android:layout_width="fill_parent"
android:layout_height="46sp"
android:gravity="left"
android:src="#drawable/nl"/>
</LinearLayout>
(I close the tags correctly later on, just showing the relevant part)
In the Graphical Layout of Eclipse it shows it the right way:
But in the Simulator and on my phone it showes it like this:
What is the best way to do this?
Fixed it.
For the ones wondering: android:scaleType="fitStart" did the job.
